What is wire electrode cutting?
Metal cutting and forming Wire EDM uses a travelling wire electrode that physically passes through the workpiece. The wire is monitored precisely by a CNC system. Like any other machining tool, wire EDM removes metal; but wire EDM removes metal with electricity by means of spark erosion.
What is CNC EDM wire cut?
Wire cut EDM equipment is run by computer numerically controlled (CNC) instruments, which can control the wire on a three-dimensional axis to provide greater flexibility. Simple cuts are done by varying the x-y coordinates of the cutter with more complex cuts achieved by adding axes of motion to the wire guides.
Where is EDM used?
The EDM process is most widely used by the mold-making, tool, and die industries, but is becoming a common method of making prototype and production parts, especially in the aerospace, automobile and electronics industries in which production quantities are relatively low.
What is the full meaning of EDM?
electronic dance music
abbreviation Music. electronic dance music: a range of genres of electronic music often played in nightclubs and characterized by a strong danceable beat: The festival lineup includes several popular EDM artists.
What is a wire EDM used for?
Wire EDM (Electrical Discharge Machining) is an electrothermal production process used to cut through metal using heat from electrical currents. Wire EDM is also known as wire-cut EDM, spark machining, spark eroding, EDM cutting, wire cutting, wire burning and wire erosion.
What is wire EDM services?
The Wire EDM (Electrical Discharge Machining) process uses a thin single strand of wire, which is fed through the workpiece in conjunction with deionized water. The wire is spooled between two guide rollers, much like the blade on a band saw, that are guided in a path controlled by the CNC.
What is the working principle of wire-cut EDM?
Wire EDM machining works by creating an electrical discharge between the wire or the electrode and the work piece. As the spark jumps across the gap, material is then removed from the work piece and the electrode.
What is wire EDM used for?
What is the working principle of wire cut EDM?
What is the principle of wire cut EDM?
Principle of wire cut EDM 2011-11-04 CNC wire cut EDM machine puts impulse voltage between electrode wire and workpiece through impulse source, controlled by servo system, to get a certain gap, and realize impulse discharging in the working liquid between electrode wire and workpiece.
What kind of wire can you cut without contact?
This is wire EDM (electric discharge machining), a process that can cut any electrically conductive material, hard or soft, even carbide or diamond. Wire EDM cuts without contact, burr free. Because the wire is so fine, you can cut small-radius inside corners or even narrow slots.
How is electrical discharge used in wire cut machining?
There is usually a low conductive liquid medium between the two, such as deionized water, which is continually flushed as the work progresses. The EDM wire electrode is moved close the workpiece, which is then gradually eroded by the electrical discharge.
How big is a wire cut in CNC?
The typical wire diameter is 0.25mm in diameter and comes in spools that are about 10 miles long, the cut is larger than the diameter of the wire, since the wire does not actually touch the work piece and “cutting” occurs due to the spark from the wire to the workpiece. The “over cut” is predictable and can be programmed into the CNC work steps.
